Charge Emitted Moving

Charge Emitted Moving appp is a professional calculation application designed for electrical engineers, mechanical designers, acoustic researchers and earthwork practitioners. It integrates four core modules, covers the precise calculation needs of multiple fields such as electrical parameters, acoustic energy, mechanical resistance, etc., and helps to efficiently complete engineering design and data verification.

Charge
- Supports point charge electric field strength and Coulomb force calculation, built-in Gaussian theorem model, customizable charge distribution and medium parameters, and real-time output of vector analysis diagram.
- Compatible with current-time integral calculation, automatically generates charge accumulation curve, and adapts to dynamic scenes such as capacitor charging and discharging.

kVA to amps
- For three-phase circuit design, it provides bidirectional intelligent conversion of apparent power (kVA) and line/phase current, and supports star/delta connection switching.
- Automatically matches power factor (0.1-1.0), synchronously displays the relationship between active power, reactive power and line voltage, and attaches circuit schematic diagram to assist understanding.

Sound Power Emitted
- Based on the acoustic measurement standard, input parameters such as sound pressure level and measurement point distance to quickly calculate the sound power level and sound power value of the sound source.
- Support free field and semi-free field environment selection, built-in A/B/C weighting network, output spectrum analysis report and noise source location suggestions.

Rolling Resistance
- For earthmoving machinery (such as rollers and bulldozers), combined with soil type (sand/clay/gravel) and tire parameters (tire pressure/ground contact area), calculate rolling resistance coefficient and energy consumption.
- Provide working condition simulation function, compare resistance changes under different operating speeds and loads, and generate optimized operating parameter recommendation tables.

From electrical system design to earthmoving project energy efficiency optimization, from acoustic laboratories to construction sites, this application takes "precision, efficiency, and ease of use" as its core, becoming an indispensable intelligent computing assistant in the engineering field.
